The assets and net worth of the exchanges are the sum of holdings in wallet addresses provided by the firms on blockchains that Nansen monitors. The analytics platform also notes that the figures are not an “exhaustive or complete statement of the actual assets/reserves held.”

The exchanges accounted for include Binance, Crypto.com, OKX, KuCoin, Deribit, Bitfinex and Huobi.

Binance, widely regarded as the largest global exchange by transaction volume, holds around $64.3 billion worth of assets across the Bitcoin, Ethereum, Tron and BNB Chain blockchains. This eclipses the other exchanges by a substantial amount.

Bitfinex has the second-largest asset holdings in reserve of the seven exchanges, according to data provided by the company. $8.23 billion of assets are held across the Bitcoin, Ethereum, Polygon, Tron, Solana, Acala, Avalanche, Cosmos, Fantom, Near, Terra and Terra Classic blockchains.

Huobi’s assets amount to a traced $3.3 billion across eight different chains. OKX reportedly holds $5.84 billion in cryptocurrency assets across the Bitcoin, Ethereum, Polygon, Arbitrum, Tron and Avalanche blockchains. 

Crypto.com holds an estimated $2.36 billion in assets across seven chains. KuCoin addresses account for $2.65 billion in assets on eight different blockchains, and Deribit holds around $1.46 billion worth of assets on the Bitcoin, Ethereum and Solana blockchains.

Nansen co-founder and CEO Alex Svanevik told Cointelegraph that the firm is planning to publish preliminary findings on the FTX situation this week. Nansen previously unpacked on-chain findings after the cataclysmic collapse of the Terra ecosystem in May 2022.
